The nitrogen sufficiency index (NSI) can be used for in-season variable rate management of nitrogen (N) fertilizer to maintain productivity of potato (Solanum tuberosum, L.) while reducing leaching losses. The objective of this study was to evaluate the implications of using high spatial resolution broad-band imagery for determining N prescriptions at… (More)
Potato yield and quality are highly dependent on an adequate supply of water. In this study, 3 years of information from thermal and RGB images were collected to evaluate water status in potato fields. Irrigation experiments were conducted in commercial potato fields (Desiree; drippers). Two water-deficit scenarios were tested: a short-term water deficit… (More)
Multiple watersheds AGNPS/GLEAMS – Pete Cooper as part of the Minnesota River Assessment Project in 1993. 10 subwatersheds were modeled. Evaluation of optical remote sensing models for crop residue cover assessment. Evaluation of predicted long-term water quality trends to changes in N fertilizer management for a cold climate.
